优势基因

Genetically engineered male sterility is one of the important methods to better use heterosis in crops.

利用基因工程创造雄性不育是更广泛地利用作物杂种优势的重要途径之一。

Our results showed that some of genes may play a role in heterosis response either through increased or decreased expression.

结果表明，有些基因通过增强或减弱表达在杂种优势现象中起一定作用。

Besides, the relationship between〓expression of maize and heterosis were analysed by means of cDNA-AFLP technique.

并且利用cDNA-AFLP技术探讨了玉米基因表达与杂种优势的关系。

These results showed that there were closely relationship between differential expression genes and heterosis at seedling stageof cotton.

上述结果表明，苗期基因表达差异与杂种优势的形成存在着密切关系。

The review is presented on several existing homogenous fluorogenic probes, and their advantages and disadvantages are discussed.

绪论部分对现有的几种均相荧光基因探针技术进行了评述，指出了它们所存在的优势与不足。

Taking advantage of a rDNA mutant,rdna-A3,which is of paromomycin resistance marker and has replication predominance over wild type r dna+,we demonstrated that among 10 000 copies of rDNA in the old macronucleus no ne could "leak" into the developing new macromucleus during conjugation.

本文以1种具有强大复制优势而且是抗药性的rDNA分子，rdna-A3，为指标，证明在接合过程中旧大核内上万个rDNA分子没有1个能进入新大核，从而在基因分子水平上证明旧大核的退化是极为彻底的。

It was a big advantage for us that we were able to reliably detect web breaks in the pre-dryer section with OnC WebDetect.

这是我们一个很大的优势，我们能够可靠地检测网络中断的预癌基因WebDetect干燥部。

It is well established that Cav1.2 encoded L-type calcium channel is prevailing component in cardiac system, while Cav1.3 encoded one dominant expressed in neuron and neuroendocrine cell. However, our and others' previous works have shown that Cav1.3 encoded LTCC was also found in the heart tissues, especially in pacemaking cells of sina atrial node, atrioventricular node and atrium.

最初人们认为心脏中的 L 型钙通道仅包括α1C（Cav1.2），但后来发现α1D（Cav1.3）在心脏中也有表达，并且优势表达于窦房结、房室结和心房，加之发现它在比较低的膜电位（－60~50mv）激活而且α1D基因敲除小鼠表现出窦性心动过缓和房室传导阻滞，所有这些都表明α1D 在维持正常的心脏节律中发挥着至关重要的作用。

How to choose strategies of handing traditional culture down is an unavoidable subject in the new situation. The author of the article thinks that clothing, which is believed to be the visiting card of a people, should be simple with symbolization, pictorialization, totems and commercialization. Handing down of the living culture should be combined with ecosystem environments and places of interest to develop its content step by step. One cultural item should be exploited in one place to keep it alive forever. We should make good use of educational, research and translating organizations, media and the Internet to propagandize old and new characters and works. Some museums should be built up to protect metallic and stone relics. Setting up ecological museums or cultural villages and parks is an effective method. We should find out a new way in which key points about the understanding of the culture are explained clearly, core advantages are developed and cutlural labour force and propaganda work are revived The most important thing is to make complete use of the laws and policies on minority self-rule to find out the best way to keep Yi's traditional culture alive.

作者认为，作为民族身份"名片"的服饰应以简明为原则尽量符号化、图案化、图腾化、商业化；作为活文化的仪式与习俗的传承，除了在经济发展的前提下以村寨为基本单位尽量保护和弘扬，要尽可能与生态环境和旅游胜地紧密结合进行单个文化主题的念珠式贯串开发，一地深入开掘一个文化内蕴，使之可以传之久远；依托教育、科研、翻译机构和文艺传媒、互联网传承新老文字及典籍文化，建立文博场馆保护金石文物；建立民族生态博物馆或民族文化村文化园等也不失为一种有效的方式；译解文化传承基因，培育核心发展优势，形成文化再生力传播力，是一条应该认真探索的道路；最重要的是要充分利用好民族区域自治政策法规，使之发挥的效益最大化，并从法律和政策上寻求最佳的传统文化传承策略。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
